It seems that a user who has not activated their wiki account in the database in the past has their user name dropped from the post method.

This only happens when the correct LFS Web credentials are input. A wrong password, invalid name etc are handled in the correct manner by displaying further prompts. The correct credentials throw the following error;

A database query syntax error has occurred. This may indicate a bug in the software. The last attempted database query was:

(SQL query hidden)

from within function "User::addToDatabase". Database returned error "1062: Duplicate entry '' for key 'user_name' (213.40.20.1)".

So far, other users with activated accounts have responded saying they have no problems, however at least one other user who also has not activated their wiki account, has confirmed the problem exists for them with the same error.

Mod note:
While this may look like a dup report, it has a different mechanism to the previously reported problem, and may be a result of the fixes that were made. Furthermore, this new report might get noticed as being new and not overlooked as noise in another thread. Please delete this as necessary. I have asked for the relevant posts to be merged with this one.

Give it another try now please.
